PENGEMBANGAN APLIKASI DESENTRALISASI (DAPPS) BERBASIS JARINGAN POLYGON UNTUK MENINGKATKAN KEAMANAN DAN INTEGRITAS REKAMAN CCTV DI BENGKEL SANUSA MOTOR

Conventional CCTV systems currently face serious challenges related to video data security, centralized storage vulnerable to attacks, and limited real-time access. This research develops the BlockCam system as a decentralized application (DApps) based on the Polygon network that integrates Blockchain technology and IPFS to address these issues. The system is Designed with a layered architecture consisting of smart contracts on the Polygon network, React-based Frontend application, Node.js Backend, and decentralized file storage on IPFS.System development is carried out through systematic methodological stages including problem identification, data collection, system Design, implementation, and testing. Smart contracts are successfully deployed on Polygon Mainnet and provide functions for managing video metadata, authenticity verification, and transparent audit trails. Integration with IPFS enables decentralized file storage that cannot be manipulated.System testing is conducted through blackbox testing with 9 test cases covering MetaMask login, CCTV live streaming, automatic recording, video upload, and authenticity verification. Test results show all features function well. Usability testing evaluation is conducted on users to measure system effectiveness in providing CCTV security solutions.The BlockCam system successfully addresses video data security issues through blockchain technology that ensures the integrity and authenticity of CCTV recordings. Smart contract implementation on the Polygon network provides transparent and immutable audit trails, while IPFS provides decentralized and secure file storage. This research successfully develops an optimal solution for enhancing the security and integrity of CCTV recordings in workshop environments through blockchain technology.
